H_Chunks
by HUEHUE
Within the current world or multiplayer server, H_Chunks marks which chunks the player has already walked through.
What it does
A HUD overlay draws a small grid in one corner of the screen. Each square represents a nearby chunk, and the grid separates visited chunks from unvisited ones. The corner, scale and grid size can be changed, and the number of grid squares is configurable as well.
Visits are saved locally and keyed to the singleplayer world or the multiplayer connection, so a player can pick up where they left off. Data is stored under the config folder. The mod can also record a scoreboard region where the game supports one, and an optional message can appear when the player steps into an already visited chunk.
The mod is client-side only, so only the client needs it and servers run without it. It is published for Fabric and targets 1.21.11 alone, under the Apache License 2.0, which covers the code without making it open source. Fabric API is required.
Key features
Visited chunk history
The mod records every chunk the player enters, so the history reflects actual exploration.
HUD chunk map
A corner overlay shows visited and unvisited chunks around the player in a small adjustable grid.
Already visited notice
An optional message appears when the player steps into a chunk that was visited before, and it can be turned off.
Reset and per-square toggles
The settings screen can reset visits for the current session and toggle individual grid squares.

Use cases
Exploring large worlds
Players crossing wide terrain can see at a glance which areas they have not yet entered.
Multiplayer servers
On a server, each connection keeps its own visit record, so returning players see their progress again.
Who it’s for: Players who explore large Fabric worlds or multiplayer servers and want a record of where they have already been. Server owners need nothing, since the mod runs on the client alone.
